A particular box, weighing 172 N, is being pushed on a horizontal floor. It requires a 43-Newton horizontal push to "break" the static friction, and 23 Newtons to keep it sliding with a constant velocity. (a) What is the coefficient of static friction? Correct: Your answer is correct. (b) What is the coefficient of kinetic friction?0.13 Incorrect: Your answer is incorrect. (c) If more stuff is put into the box, bringing its total weight up to 210 N, the maximum static friction will now be Changed: Your submitted answer was incorrect. Your current answer has not been submitted. Dimensionally incorrect. Please check the type or dimension of your unit. and the kinetic friction will be ?
